제1도는 본 고안의 단면도.1 is a cross-sectional view of the present invention.
제2도는 본 고안의 요부 분해 사시도.Figure 2 is an exploded perspective view of the main part of the present invention.
제3도는 종래 펌프의 단면도이다.3 is a cross-sectional view of a conventional pump.
본 고안은 펌프의 누수방지 장치에 관한 것이다.The present invention relates to a leak prevention apparatus of the pump.
종래 메카니칼실링으로 기밀을 유지시키는 회동축 주연부에서 누수 현상이 발생 되었으며, 이 누수원인을 발견하지 못해 펌프자체를 교환하여 주거나 메카니칼실링 어셈블리를 통체로 교환하여 주었다.The leak occurred at the periphery of the rotating shaft that maintains hermeticity with the conventional mechanical sealing, and the pump itself was replaced or the mechanical sealing assembly was replaced with the cylinder because the leak cause was not found.
본고안은 종래 메카니칼실링으로 기밀이 유지되는 펌프에 있어 누수원인을 발견함에 따라 본 고안이 안출된 것으로, 종래 펌프의 구조 및 작동상태를 살펴본후 본 고안을 살펴보면 다음과 같다.The subject of the present invention is that the present invention has been devised as the cause of leaks in a conventionally sealed pump is maintained by mechanical sealing. The present invention will be described after examining the structure and operating state of a conventional pump.
제3도는 종래 펌프의 단면도로 그 구조는 다음과 같다.3 is a cross-sectional view of a conventional pump, the structure of which is as follows.
즉, 모타(M)의 회동축(21)은 펌프(22)격벽(22')에 삽치된 부동시이트(23)와 이에 삽착된 메카니칼실링(24)의 중앙 구멍에 끼워진후 실링(25)을 삽착하고 있는 패킹링(26)의 중앙구멍에 삽치되며, 그 단부에는 임펠러(27)가 고정되어진다.That is, the rotation shaft 21 of the motor M is inserted into the center hole of the floating sheet 23 inserted into the partition 22 'of the pump 22 and the mechanical sealing 24 inserted therein, and then the sealing 25 is opened. It is inserted into the center hole of the packing ring 26 inserted, and the impeller 27 is fixed to the end part.
상기 메카니칼실링(24)과 실링(25)의 확실한 밀착을 위하여 패킹링(26)과 임펠러(27)사이에는 스프링(28)이 삽치되어지며, 패킹링(26)주연부에는 모타의 회동축(21)과의 기밀을 유지하기 위하여 코일링 스프링(29)이 역시 삽치되어 진다.The spring 28 is inserted between the packing ring 26 and the impeller 27 to ensure a close contact between the mechanical seal 24 and the seal 25, and the rotational shaft of the motor 21 is formed at the periphery of the packing ring 26. The coiling spring 29 is also inserted in order to maintain airtightness.
이와같은 구조를 갖는 펌프(22)에 있어 전원의 인가와 동시 모타(M)가 구동되는 시동 초기에 있어서는 메카니칼실링(24)과 당접되어진 실링(25)의 밀착력이 모타(M)의 초기 구동력보다 세기 때문에 패킹링(26)는 회동축(21)과 동시에 회전되지 못하고 약간의 시차를 두고 뒤이어 패킹링(26)이 회동축(21)의 구동력에 의해 회전하게 된다.In the pump 22 having such a structure, the adhesion of the mechanical seal 24 and the seal 25 in contact with the mechanical seal 24 is greater than the initial driving force of the motor M at the initial stage of starting the motor and driving the motor M simultaneously. Because of the strength, the packing ring 26 is not rotated at the same time as the rotation shaft 21, but with a slight parallax, the packing ring 26 is rotated by the driving force of the rotation shaft 21.
이와같이 회동축(21)과 같이 회전되지 못하고 시차를 두고 회전되는 패킹링(26)는 회동축(21)과의 시차만큼 그 내경에 마찰력이 발생하게 되며, 이 마찰력은 패킹링(26)내경을 부분 마모시켜 장시간 펌프(22)을 사용함에 있어 패킹링(26)내경의 마모 부분을 따라 누수가 발생하게 된다.As described above, the packing ring 26, which is not rotated like the rotation shaft 21 and rotates with a parallax, generates friction force in the inner diameter of the packing ring 26 with the parallax with respect to the rotation shaft 21, and this friction force causes the inner diameter of the packing ring 26 to decrease. When the pump 22 is used for a long time by partial wear, leakage occurs along the wear portion of the inner diameter of the packing ring 26.
이와같이 패킹링(26)내경의 마모로 인한 누수를 해결하기 위하여 본 고안은 상기 언급한 종래 펌프(22)에 있어서, 패킹링(26)과 임펠러(27)사이에 원통체를 삽치시켜 회동축(21)의 회전과 동시 패킹링(26)을 회전토록하여 패킹링(26)내경에 시차구동에 의해서 발생되는 마찰력에 인한 마모를 제거하여 누수가 되는 원인을 제거토록한 것으로, 이를 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Thus, in order to solve the leakage caused by the wear of the inner diameter of the packing ring 26, the present invention in the conventional pump 22 mentioned above, by inserting a cylindrical body between the packing ring 26 and the impeller 27 to rotate the rotating shaft ( At the same time, the packing ring 26 is rotated so as to remove the wear caused by the frictional force generated by the parallax driving in the inner diameter of the packing ring 26, thereby eliminating the cause of leakage. The detailed description is as follows.
설명에 있어 종래 펌프와 동일한 부분은 동일한 부호를 사용하였다.In the description, the same parts as in the conventional pumps have the same reference numerals.
즉, 모타(M)의 회동축(21)은 펌프(22) 격벽(22')에 삽착된 부동시이트(23)와 이에 삽치된 메카니칼실링(24)의 중앙구멍에 끼워진후 실링(25)을 삽착하고 있는 패킹링(26)의 중앙구멍에 삽치되며 그 단부에는 임펠러(27)가 고정되어지며, 상기 패킹링(26)과 임펠러(27)사이에 스프링(28) 이 삽치되며, 패킹링(26)주연부에 코일링 스프링(29)이 삽치되는 종래 펌프(22)에 있어서, 수개의 돌기(1)를 갖는 원통체(2)를 상기 패킹링(26)과 임펠러(27)사이에 삽치토록한 것으로, 도면중 미설명부호 30은 흡입구, 31는 배출구이다.That is, the rotation shaft 21 of the motor M is inserted into the center hole of the floating sheet 23 inserted into the partition 22 'of the pump 22 and the mechanical sealing 24 inserted therein, and then the sealing 25 is opened. It is inserted into the center hole of the packing ring (26) being inserted and the impeller (27) is fixed at the end thereof, and the spring (28) is inserted between the packing ring (26) and the impeller (27), and the packing ring ( 26) In a conventional pump 22 in which a coiling spring 29 is inserted in a peripheral portion, a cylindrical body 2 having several projections 1 is inserted between the packing ring 26 and the impeller 27. In the drawings, reference numeral 30 denotes an inlet port, and 31 denotes an outlet port.
이와같은 구조를 갖는 본 고안의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention having such a structure as follows.
모타(M)에 전원이 인가되어 회동축(21)을 구동시키게되면 회동축(21)단부에 삽착된 임펠러(27)가 동시에 회전을 하게 되며, 임펠러(27)에 삽치된 원통체(2)의 돌기(1)에 의해 원통체(2)는 임펠러(27)와 동시 회전을 하여 원통체(2)타측 내경에 삽치된 패킹링(26)을 회전시킨다.When power is applied to the motor (M) to drive the rotating shaft 21, the impeller 27 inserted into the end of the rotating shaft 21 is rotated at the same time, the cylindrical body 2 inserted into the impeller 27 By the projections 1 of the cylindrical body 2 rotates simultaneously with the impeller 27 to rotate the packing ring 26 inserted in the inner diameter of the cylindrical body (2).
따라서, 패킹링(26)은 시차의 간격없이 회동축(21)과 같이 회전 하게 된다.Therefore, the packing ring 26 is rotated together with the rotation shaft 21 without the time difference.
이와같이 원통체(2)는 패킹링(26)을 회동축(21)과 동시에 회전되게 하여 패킹링(26)내경에 종래와 같이 시차 구동으로 인한 마모가 발생하지 않아 누수의 원인이 없어진다.Thus, the cylindrical body 2 rotates the packing ring 26 and the rotating shaft 21 at the same time, so that the inner ring diameter of the packing ring 26 does not cause wear due to parallax as in the prior art, and thus causes no leakage.
이와같이 본 고안은 종래 펌프에 간단한 원통체를 삽입하여 누수의 원인을 제거토록한 것으로, 기존 펌프의 내부구조 변경없이 그대로 적용시킬 수 있는 아주 유용한 고안인 것이다.As such, the present invention is to remove the cause of the leakage by inserting a simple cylindrical body in the conventional pump, it is a very useful design that can be applied as it is without changing the internal structure of the existing pump.
